Set a time slot everyday where you will sit down and do nothing but work on creating your art. Doesn't matter if it's good or bad, your only job is to sit there and create for the whole time period. That's the key, is consistently trying to do it.
I highly recommend reading the The War of Art by Steven Pressfield, he goes into this a lot more - https://www.amazon.com/War-Art-Through-Creative-Battles/dp/1...
He also talks about the concept of "Resistance", which is basically a force of nature that's works against you getting things done, and that gets stronger the closer you are towards doing work that is meaningful to you.
I write only in cafés, so watching other people is my main distraction, but surfing the net and checking emails is also nice from time to time. Procrastination is an important part of writing, I don't see what the problem is with it. Are there still writers who are paid by page/minute?
Personally, I don't trust machine gun writers' writing very much. Whether it's creative or scientific writing, nobody can think that fast, and producing good texts takes a lot of time, corrections and rewriting anyway.
Now if I only knew how to sell my German Sci-Fi novels and make at least a little bit of money from them. That's the real problem. :-/
Sadly, in the German book market Sci-Fi is almost dead. The reason for this is not so bad, though. There are so many outstanding English writers that originals and a few translations here and there cover almost the entire program segments of the traditional publishers.
Unfortunately, Amazon is not the ideal solution either. They are kind of evil and universally hated by bookstores. It feels a bit like selling your soul to the devil.
